Distributed Storage Systems Research
Current Projects
-
- Leading an effort to build a staging area using SSDs on large supercomputers that can be used to accelerate I/O and post-processing pipelines of large (e.g., 100,000-core) jobs.
- PI on the NSF HECURA project (04/2010 - 03/2013).
- Leading the development of a checkpoint storage system for HPC apps at all granularity (loosely coupled to tightly coupled, i.e., from a desktop grid to clusters to large supercomputers)
-
- PI on an effort to build robust storage management for the supercomputer machine-room and beyond (LDRD 10/2006 - 10/2008).
Previous Projects
-
- Led an effort to build terabytes of cache/scratch space for transient, bulk, immutable data from loosely connected, commodity, user desktop storage resources.
- Co-PI on a broader effort to provide reliability, availability and serviceability for terascale supercomputers. I am delving into the data availability aspect (10/2004 - 10/2006).
-
- PI on an effort to build robust storage management for the supercomputer machine-room and beyond (LDRD 10/2006 - 10/2008).
-
- An effort to transform the HPC center scratch as a cache.
